The Amazing World of Gumball: The Movie – idea

I have a movie idea and wanted quick feedback

The Void starts consuming Elmore Bobert sends Gumball and Darwin to the past Nicole and Richards high school days Gumball becomes a famous guitarist but ruins it by using playback out of insecurity He and Darwin fight end up in prehistory reconcile and finally face The Void to save their family and Rob

The Void isnt destroyed the final shot shows a small glitch in the sky

Would this feel in character for Gumball
